The average facade temperature of the globe has augmented
more than 1 degree Fahrenheit since 1900 and the speed of warming has
been almost three folds the century long average since 1970. This
increase in earth’s average temperature is called Global warming. More
or less all specialists studying the climate record of the earth have
the same opinion now that human actions, mainly the discharge of green
house gases from smokestacks, vehicles, and burning forests, are
perhaps the leading power driving the fashion.

The gases append to the planet's normal greenhouse effect, permitting
sunlight in, but stopping some of the ensuing heat from radiating back
to space. Based on the study on past climate shifts, notes of current
situations, and computer simulations, many climate scientists say that
lacking of big curbs in greenhouse gas discharges, the 21st century
might see temperatures rise of about 3 to 8 degrees, climate patterns
piercingly shift, ice sheets contract and seas rise several feet. With
the probable exemption of one more world war, a huge asteroid, or a
fatal plague, global warming may be the only most danger to our planet
earth.

Global Warming is Inspiring Scientists to Fight for Awareness

Scientists
all over the world are making predictions about the ill effects of
Global warming and connecting some of the events that have taken place
in the pat few decades as an alarm of global warming. The effect of
global warming is increasing the average temperature of the earth. A
rise in earth’s temperatures can in turn root to other alterations in
the ecology, including an increasing sea level and modifying the
quantity and pattern of rainfall. These modifications may boost the
occurrence and concentration of severe climate events, such as floods,
famines, heat waves, tornados, and twisters. Other consequences may
comprise of higher or lower agricultural outputs, glacier melting,
lesser summer stream flows, genus extinctions and rise in the ranges of
disease vectors. As an effect of global warming species like golden
toad, harlequin frog of Costa Rica has already become extinct. There
are number of species that have a threat of disappearing soon as an
effect of global warming. As an effect of global warming various new
diseases have emerged lately. These diseases are occurring frequently
due to the increase in earths average temperature since the bacteria
can survive better in elevated temperatures and even multiplies faster
when the conditions are favorable. The global warming is extending the
distribution of mosquitoes due to the increase in humidity levels and
their frequent growth in warmer atmosphere. Various diseases due to
ebola, hanta and machupo virus are expected due to warmer climates. The
marine life is also very sensitive to the increase in temperatures. The
effect of global warming will definitely be seen on some species in the
water. A survey was made in which the marine life reacted significantly
to the changes in water temperatures. It is expected that many species
will die off or become extinct due to the increase in the temperatures
of the water, whereas various other species, which prefer warmer
waters, will increase tremendously. Perhaps the most disturbing changes
are expected in the coral reefs that are expected to die off as an
effect of global warming. The global warming is expected to cause
irreversible changes in the ecosystem and the behavior of animals.

A
group of scientists have recently reported on the surprisingly speedy
rise in the discharge of carbon and methane release from frozen tundra
in Siberia, now starting to melt because of human cause increases in
earth’s temperature. The scientists tell us that the tundra is in
danger of melting holds an amount of extra global warming pollution
that is equivalent to the net amount that is previously in the earth's
atmosphere. Likewise, earlier one more team of scientists reported that
the in a single year Greenland witnessed 32 glacial earthquakes between
4.6 and 5.1 on the Richter scale. This is a disturbing sign and points
that a huge destabilization that may now be in progress deep within the
second biggest accretion of ice on the planet. This ice would be enough
to raise sea level 20 feet worldwide if it broke up and slipped into
the sea. Each day passing brings yet new proof that we are now in front
of a global emergency, a climate emergency that needs instant action to
piercingly decrease carbon dioxide emissions worldwide in order to turn
down the earth's rising temperatures and avoid any catastrophe.

It is not easy to attach any particular events to global warming, but
studies prove the fact that human activities are increasing the earth’s
temperature. Even though most predictions focus on the epoch up to
2100, even if no further greenhouse gases were discharged after this
date, global warming and sea level would be likely to go on to rise for
more than a millennium, since carbon dioxide has a long average
atmospheric life span.

You Can Help Fight Global Warming

Many
efforts are being made by various nations to cut down the rate of
global warming. One such effort is the Kyoto agreement that has been
made between various nations to reduce the emissions of various green
house gases. Also many non profit organizations are working for the
cause. Al Gore was one of the foremost U.S. politicians to heave an
alarm about the hazards of global warming. He has produced a
significantly acclaimed documentary movie called "An Inconvenient
Truth," and written a book that archives his advice that Earth is
dashing toward an immensely warmer future. Al Gore, the former vice
president of United States has given various speeches to raise an
awareness of global warming. He has warned people about the ill effects
of Global warming and its remedies.

But an
interesting side of the global warming episode is that there are people
who do not consider global warming as something that is creating a
problem. Skeptics of global warming think that global warming is not an
ecological trouble. According to the global warming skeptics, the
recent enhancement in the earth's average temperature is no reason for
alarm. According to them earth's coastlines and polar ice caps are not
at a risk of vanishing. Global warming skeptics consider that the
weather models used to establish global warming and to forecast its
impacts are distorted. According to the models, if calculations are
made the last few decades must have been much worse as compared to
actually happened to be. Most of the global warming skeptics believe
that the global warming is not actually occurring. They stress on the
fact the climatic conditions vary because of volcanism, the obliquity
cycle, changes in solar output, and internal variability. Also the
warming can be due to the variation in cloud cover, which in turn is
responsible for the temperatures on the earth. The variations are also
a result of cosmic ray flux that is modulated by the solar magnetic
cycles.

Global Warming Skeptics

The
global warming skeptics are of the view that the global warming is a
good phenomenon and should not be stopped. There are various benefits
of global warming according to them. According to the skeptics, the
global warming will increase humidity in tropical deserts. Also the
higher levels of carbon dioxide in the atmosphere trigger plant growth.
As predicted, due to the global warming the sea levels will rise. But
this can be readily adapted. Another argument of global warming
skeptics is that earth has been warmer than today as seen in its
history. The thought is that global warming is nothing to get afraid of
because it just takes us back to a more natural set of environment of
the past. Animals and plants appeared to do just fine in those eras of
warm climate on the earth. According to few skeptics, the present
chilly climate on the earth is an abnormality when judged over the
geographical scale. Over geologic time, the earth’s mean temperature is
22 degrees C, as compared to today's 15.5 degrees C.
